The airworthiness directive

59-10-03 CESSNA: Applies to Cessna Models 172, Serial Numbers 28000 Through 36003; 180, 180A, Serial Numbers 30000 Through 32991; 182, 182A, Serial Numbers 33000 Through 34500.

Compliance required by July 15, 1959.

The Narco Model 300 position light flasher is of non-fail-safe design and to comply with the Civil Air Regulations a three position switch should be installed to permit steady operation of the lights in case of flasher failure. In addition, a means should be provided to enable the pilot to tell when the flasher has failed. Plexiglas reflectors at the wing tip lights or a monitor light on the instrument panel are acceptable means. The Van Dusen flasher (Cessna P/N 0511309-1) is acceptable as a fail-safe design.

(Cessna Service Letter 180/182-41 covers this same subject.)
